Banshee of Generation X (Marvel Comics)


(Sean Cassidy)


Banshee (Sean Cassidy) appeared in 1967, in X-Men stories.

At first he was a bad guy, drawn in a startlingly racist way (depictions of Irish folks with monkey-like features were still a thing back then). So in some ways his “real” debut was in 1975, in the landmark Giant-Size X-Men, when he was recruited to join the all-new, all-different X-Men.

Since we like this guy this writeup was done *very* early. Back when we were almost entirely about hashing out DC Heroes RPG stats rather than writing character profiles. In some far mythical future we’ll have time to completely overhaul it, but in the meanwhile all we can do is look at it and scream.

Powers and Abilities

Sean is a free soul who gets irate only when he thinks about his villainous cousin Black Tom, or when someone close to him is threatened. He is a hopeless ladies’ man who has carried a torch for Moira MacTaggart for years. He has a fondness for American westerns.

DC Universe History

Banshee was an Interpol operative who went rogue when he was held back from his investigations of an international serial killer(see Generation X for this). He wound up on the wrong side of the law when he tracked down the killer and killed him to stop his predations, and became a wanted criminal himself.

He wound up taking refuge in the Suicide Squad, and, eventually becoming a more respected meta, found himself throwing in with the Doom Patrol.

Previous Statistics

Banshee seems to be one of the more stable mutants in Marvel’s répertoire. He has changed surprisingly little over the years, most changes being character-driven background revelations or subplot involvements (i.e., his Power Complication subplot where he lost his Sonic powers). When he has had his powers, they remained at a fairly static level.

Before her death from the Legacy Virus, Sean had Moira MacTaggart as a Dependent (10 Points).

70 HPs is for Banshee as an active X-Man ; before or after that he tended to operate with 30 HPs instead.
